"It sickens me that a young, talented artist who had traveled the world to pursue his passion was murdered here, thus reinforcing the stereotypes for many about our city of Detroit," Wayne County Prosecutor Kym Worthy said when charges were announced in September.

Berreni grew up in Paris and began covering the walls of his neighborhood in the 20th arrondissement when he was 15, the newspaper said.

Dionte Travis, 21, was the last of three adults and one teen to be convicted in Berreni's death.

He is believed to be the one to have shot Berreni in the face after spotting him near basketball courts at the now-demolish housing projects.

They stole his wallet and about $300 which Berreni had hidden inside his shoes.

Prosecutors told the court that Travis used his share to buy marijuana and potato chips.

He was sentenced to 30 to 60 years in prison after being convicted of felony murder, a spokeswoman for the prosecutor's office told AFP.
